    Please refer to the service manual for R4-Mechanism Chassis. (Order No. VRD0202010C8) 2. The Model No. is indicated on the Schematic Diagram and Circuit Board Diagrams as follows. Model No. Indication Mark NV-VP31GL (GL) NV-VP31GC (GC) NV-VP31GCS (GCS) 1.2. ABOUT LEAD FREE SOLDER (PbF) Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB.
  • Page 4 2.1. GENERAL GUIDELINES 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, confirm that all the protective devices such as insulation barriers, insulation papers shields are properly installed.

  • Page 5: Prevention Of Electro Static Discharge

    4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to do the hot checks, leakage current must not exceed 1/2 milliamp.

  • Page 6: Precaution Of Laser Diode

    5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, alminum foil or comparableconductive material).

    5. PREVENTION OF STATIC ELECTRICITY DISCHARGE The laser diode in the traverse unit (optical pickup) may break down due to static electricity of clothes or human body. Use due caution to electrostatic break down when servicing and handling the laser diode.
  • Page 10 5.1. Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 5.1.1.

    it. Use caution when handling the cable. 4. The half-fixed resistor for laser power adjustment shall not be adjusted. Do not turn the resistor. 6. GENERAL DESCRIPTION 6.1. OPERATING INSTRUCTIONS 6.2. SERVICE CAUTION-1 When the Microprocessor IC6001 and/or Back-up battery B7751 are replaced, read the following procedure carefully and proceed it.
  • Page 12 1. Be noted that stored TV broadcast channels might be erased. ( Because the user may have stored TV broadcast manually rather than using "Auto Tuning". ) NOTE: During servicing, do not make a short circuit between IC6001-pin 37 (5V) with other line/ Components otherwise IC6001 may be broken.
